The type of cotton-presses to which the in-V I vention relates is that intended to form bales cylindrical in shape by winding a continuous sheet or bat in spiral layers on a core or spindle, the sheet or bat being simultaneously subjected to pressure, whereby a very dense 2o and compact bale will be obtained.. The means employed for compressing the sheet or bat as it is thus wound in place on the core or spindle comprise, preferably, two baling-A rolls; but a greater number of baling-rolls z5 may be employed, or instead thereof a belt may be used to effect the compression. In the operation of such presses it will be convenient to provide means by which the core or spindle on which the bale is formed may 3o be released at both ends from one side of the press and, preferably, by which the core may. be simultaneously released at both ends tol allow for the removal ofthe inished bale; and the present invention relates, broadly, vto

mechanism by which this result will be ac-` complished. Generieally stated, the invention consists in providing the core or spindle of arotary baling-press with suitable supports at each end which will allow for the rotation of the core or spindle and to combine with saidv supports suitable mechanical devicesby whichfrom' one side of the press the said supports may be preferably simultaneously withdrawn from both ends of the core or spindle,` so as to release the same when the finishedba'le is to be' removed. I preferably employ a tubular core and engage within each end thereof a suitable supporting-pin, by which the core will be sustained in its position and be allowed to rotate, and I mount above the core and eX- tend parallel therewith a rotatable shaft, having connections with said supporting-pins and by which they may be simultaneously withdrawn` from engagement with the core or be engaged therewith.

Inorder that my invention may be better under`stood,attention is directed to the ac companying drawings, forming a part of this specification, and in 'which-.

Figure `1 is a side view of a two-roll cottonpress, showing my present improvements applied y thereto; and Fig. 2, a cross-sectional view through the line ot' the core on a somewhat-enlarged scale. 6 5 l In both of the above views corresponding parts are represented by the same numerals of reference.

A1 1 represent the side frames of the press,

2 the fixed baling-roll, mounted in stationary 7o bearing-blocks, and 3 the movable baling-roll, mounted in movable bearing-blocks working in slotsx20 in the side frames. Pressure is applied to the movable baling-roll 3 in any suitable way, such as by means of a hy- 75 draulic cylinder 23. The two baling-rolls 2 and 3 are positively driven in the same direction and'at thesame peripheral speed by any `suitable mechanism-such as, for example, by sprocket-chains 55 and 56, which are so 8o arranged as to allow for the relative separa` tion ofthe rolls.

. 4 represents the core or spindle, which is carried between the baling-rolls 2 and 3, with itsaxis in substantially the same plane as the 8 5 axes lof said rolls. The core or spindle 4 is illustrated as being tubular in form; but it is obvious that it may be a solid bar having recesses or sockets in its ends.

17 are'movablebearing-blocks which sup 9o port the core, said bearing-blocks working in s'lotsl in the side frames. Carried by the bearing?. blocks 17 are supporting-pins 63, whichl engage the ends of the core and sustain 4the same in its positionbetween the bal- 95 ing-rolls; These supporting-pins are preferably oarried in the ends of `screwthreaded shafts 18, engaging within the bearing-blocks 17. It will be obvious that by simultaneously rotating the said shafts, each in the proper rooV the movable bearing-blocks 17, and mounted in said standards is a shaft 67, which extends above and parallel with the core 4. On this shaft are two sprocket-wheels 66. The shaft may also be provided with a crank or handle 69 at each end thereof, so that it may be rotated from either side ofthe press.

64 64 are sprocket-wheels which are splined` upon the screw-threaded shafts 18 and which, therefore, will rotate the said shafts and at the same time allow longitudinal movement of said shafts. lLateral movement of the sprocket-'wheels 64 may be prevented by forming-'small fingers on the movable bearingboXes 17, which engage in anV annular groove concentric with each sprocket'- wheel, as shown. The sprocket-wheels 64 and 66 at each side ofthe machine. are connected by a sprocket-chain 65.

When it is desired to remove the bale from the press after the bale has been finished, the shaft 67 will be rotated by the handle or crank 69, which movement will simultaneously rotate the sprocket-wheels 64, and the screwthreadedshafts 18 will therefore be' turned relatively to the bearing-boxes 17, so as to move laterally therein and effect a simultaneou's disengagement of the supporting-pins fromthe core.

With the specific mechanism described it will of A'course be necessary to make one ofthe shafts'18 left-l1anded and' the other right# handed.

It'will be understood that the' specific op' erating mechanismv described may be varied iny many respects without departing from the essential spirit ofthe invention, which, broadly considered, consists in providing a support for-each end'of the core or spindle used in a baling-'press for making cylindrical bales'and in providing suitable mechanism by which from one side ofthe p'ress'the said supports may be, preferably simultaneously withdrawn from engagement with the coreor spindle. It will of course be understood that instead of providing supporting-pins 63,which engage' in sockets or recesses formed in the core'orwhich engage with a tubular core, it will be possible' to engage the ends ofthe core within sockets or recesses formed in theends of the shafts 18 or their equivalents or formed in' the bearing-boxes 17 themselves, provision being made when the bale has been finished to provide for the movement of said bearingboxes. These modifications are so obvious and will be so readily understood'by those skilled lin the-'art 'that illustration thereof is not necessary.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

1. VThe combination `in a rotary press, of

withdrawable baling-core-supporting centers, a core mounted on said centers, and means for withdrawing and advancing said centers from one side of the press and independently yof the other movable parts of the press, substantially as set forth. 2L The combinationina rotary cotton-press, of two baling-rolls, means for driving said rolls, withdrawable baling-core-supporting centers, a core mounted on said centers between said rolls, and means for advancing and withdrawing' said supporting-centers from one side `of the press independently of the movable parts of the press, substantially as set forth.

3. The combin'ationin arotary cotton-press, of kwithdrawable baling-core-supporting Vcenters mounted in sliding bearing-blocks, and a connection between said centers whereby they may be advanced and withdrawn simultaneously and independently of the other movable parts of the press, substantially as setforth.

4. The combination in a rotary cotton-press, 0f two -b'aling-rolls, meansfor'driving said rolls, withdrawable baling core supporting centers mounted in sliding bearing-blocks, and a lconnection between said centers'whereby they may be advanced and withdrawn simultaneously independently of the other movable parts of' the press, substantially as set forth.

5. In a' cotton-press of the character described, the combination of two baling-rolls, meansfor driving said rolls, a core mounted between the same,'means for supporting said core at each end thereof, and independent means for simultaneously releasing both ends of the core, substantially asset forth'.

6. In a cotton-press ofA the character'described, the combination of two baling-rolls inv substantially the same plane, means for operating said rolls, a core mounted vbetween said rolls, .movable bearing-pieces for the ends of said core, and .an operating-shaft connected with said bearing-pieces for simultaneously moving the same out of engagement kwith the core, said operating shaftV being `mounted out of the plane of the rolls, substantially as set forth.
